After defeating the five Elemental sisters and retrieving their artifacts you finally create the heart of1 the elements, which glows brightly in your hands.

You hold the heart tightly to your chest absorbing it and feeling a second heartbeat... Suddenly the Elemental sisters appear around you looking dazed and confused.

Anahita: O-ow... my head hurts...

Brimstone: Mine too... Wait- it's that brat who killed me!!!

Cloud: Brimstone calm down... I'm pretty sure they killed us all-

Rarity Sand: Sorry to interrupt you Cloud, but look!

Original Sand: T-they actually made the heart of the world...
